Re: How do I correctly wire an auxiliary battery 99 Suburban using existing GM equip?
Aux A & Aux B are NOT for connecting the battery. Those posts are there for things that you might ADD. There is a factory option or two that use them, I can't remember what right now. Camper/Trailer wiring is the most commonly added feature.
Give me a few minutes and I think I can have your wiring diagram. Help me out here, 350/454, 1500/2500?
